It is now feasible to make a prized material for spintronic devices and semiconductors: monolayer graphene nanoribbons with zigzag edges. Miniscule ribbons of graphene are desirable building blocks for semiconductor devices because of their predicted electronic properties, but making these nanostructures has remained a challenge. A team of researchers from China and Japan have devised a new method to make the structures in the lab; their findings appear in the current issue of Applied Physics Letters.
“Many studies have predicted the properties of graphene nanoribbons with zigzag edges,” said Guangyu Zhang, senior author on the study. “But in experiments it’s very hard to actually make this material.”
